3 Claims. (Ci. 68-180) This invention relates to the dyeing art, and more particularly to means for enclosing the space above the tank of a dyeing jig to prevent escape of steam therefrom.

A dye jig as usually constructed comprises a tank and pair of arbors. The arbors are mounted above the tank, and are rotated by suitable mechanism to wind fabric back and forth between them, the fabric passing under rollers in the dye-containing tank as it passes from one arbor to the other. Past constructions intended to enclose the space above the tank have been unsatisfactory in many respects.

It is important that when the jig is opened, the space above the jig shall be as open and free of obstructions as possible, to facilitate loading. Also, any doors which by their mere motion cause steam to be ejected on the operator are objectionable. As there may be a slight head of steam over the dye bath, it is preferable that the initial opening of the enclosure be such that discharged steam is blown away from the operator.

As the usual dye works is cramped, the existing jigs being installed with very little clearance, it is desirable that the enclosure selected be as small as possible, and not have swinging doors for which there may be insufficient room.

One other desirable feature is an interior shape of the enclosure which will prevent dripping of condensate on the fabric, as such dripping tends to produce spots on certain types of fabric.

It is therefore an object of the present invention to produce an enclosure for a dye jig which will not unduly increase the space requirements of the jig, which can be opened without danger to the operator from escaping steam, and will not drip condensate upon the fabric.

Referring now to the drawings:

Figs. 1 and 2 are perspective views of a jig embodying a preferred form of the present invention, with the enclosure in closed and open conditions respectively;

Fig. 3 is a section transverse the axis of the jig shown in Fig. 1;

Fig. 4 is a fragmentary section taken on line 44 of Fig. 3;

Fig. 5 is a fragmentary section taken on line 55 of Fig. 3; and, Fig. 6 is a perspective view of a door member disassociated from the rest of the structure with which it is used.

A dye jig is shown comprising a pair of pillar members 10 at each end, supporting arbors 11 which are rotated by machinery associated with the pillars. A tank, with ends 12, a bottom 12a and sloping sides 12b is formed of sheet material. Scum troughs 13, and angle members 19, running lengthwise of the tank, are secured to the pillars and serve to support the tank and its contents.

The structure so far described is conventional. The purpose of this invention is to provide a structure which will form with the above described jig an enclosure for the tank contents, together with the arbors and their load of fabric. The general shape of the surrounding structure insofar as space requirements is concerned is cylindrical, with sliding panels or doors which are curved to conform to this shape, and are mounted on circular tracks to slide out of the way when the enclosure is opened.

As shown in Figs. 3 and 4, a circular track 15 is provided at each end of the enclosure. As two U-shaped circular channels are desired at each end of the enclosure, they are formed by bending and welding two angles and a bar. Angle 16 has its flange 16a welded to a bar 18, as has angle 17 its flange 17a. The flanges 16a and 17a are 2,698,535 Patented Jan. 4, 1955 in the plane of the circle into which the angles are bent, while flanges 16b and 17]) extend parallel to the bar 18. Thus flange 16b and bar 18 form the sides of one channel, and flange 17b and bar 18 form the sides of the other concentric channel, which channels are intended to sup port the doors to be described.

To an upper segment of each of these circular structures is attached a sheet 20, which may be welded to the flange 17a of angle 17. A second sheet 21 extends from the edge of sheet 20 to the top of the tank end 12. This sheet 21 is attached by rivets or screws to the circular structure after assembly on the jig. A strip 22 secured to the lower edge of sheet 21 forms therewith a channel for the reception of the tank rim, as shown in Fig. 5.

Brackets 23, secured to the angles 17 and 16 at various points, engages the pillars 10 and the angles 19, to fix the tracks and sheets with respect to the pillars 10 and with respect to the tank supported by the pillars.

For the purpose of extending the sides of the tank out to the circular track, to cooperate with the panels or doors sliding therein, an apron 24 is provided at each side of the tank. Vertical strips 25, secured to the scum troughs are attached to the aprons 24 and thus support the aprons. Each of the aprons 24 has a vertical portion 27, to cooperate with a movable door to form a suitable seal. The aprons 24 are secured to the end sheets 21 by screws or the like passing through the flanges 28 formed on the aprons.

The doors employed are in the shape of approximately a quarter of a cylinder each. At each end, an end member 30, formed of an angle, is provided, curved to correspond to, the respective track or channel in which the door is to ride. Extending between members 30 are straight angle members 31, the curved members and the straight members thus forming a framework for panelling 32, in the form of sheet material welded to the angle members. Windows 33 of curved glass may be provided, to permit gnspection of the dyeing process without opening the oors.

As shown in Fig. 3 and in Fig. 6, the curved members 34) are approximately three-quarters of a circle in extent. Suitably positioned on each member 30, at the end remote from the panelling of the doors is a lead weight 34, for counterbalancing the entire structure. This weight need be only great enough to bring the center of gravity of the entire door to the center of curvature of the tracks. With the weight of the movable structure so distributed there is no tendency for the door to move from any position in which it is set.

For the purpose of permitting easy motion of each door, a series of rollers 35 is mounted on each angle member 30 to engage the sides of the channel in which it runs, while a series of rollers 36 also mounted on each angle member engage the bottom of the track channel.

For the purpose of permitting loading of the jig from drums or reels, channels 38 are secured inside the enclosure. These channels 38 are supported on plates 39, bolted to plates 40, which are in turn Welded to flange 17b of the inner track-forming angle 17. The lower ends of the channels 38 are secured to Z plates 41, which are in turn bolted to the rings 42. The rings 42 are part of, or attached to the bearings for the arbors 11, and are thus fixed to the pillars 10. To load the machine, a roll of fabric on a drum is dropped to rest on one of the arbors. The shaft of the fabric bearing drum is held against lateral or axial displacement by the walls of the channels 38. By causing the arbor upon which the fabric rests to rotate, the fabric is wound on the arbor. To prevent the escape of steam during this operation, the jig enclosure may be shut.

It is to be understood that considerable modification of the above structure can be made without departing frcimlthe invention as expressed in the following claims.
